Remove empty expected_authority_names array in CodeSignatureVerifier arguments

[homebysix]

As long as there is a valid requirements argument, the expected_authority_names argument is not needed for code signature verification. This pull request removes the unnecessary empty expected_authority_names array.

Thanks for considering!

Disregard — I see that CodeSignatureVerifier is used multiple times in some of these recipe chains, so it makes sense that expected_authority_names would need to be overwritten for subsequent app verifications.
